Integrated storage battery pack fusing device easy to operate and provided with visual protective cover

Abstract

According to the integrated storage battery pack fusing device easy to operate and provided with the visual protective cover. The insulating protective cover and the insulating base are arranged, and the main fuse, the signal fuse, the microswitch and other components are arranged in the corresponding insulating cavities, so that no exposed electrified part exists outside the device, and personal safety is guaranteed. And when the insulating protective cover is in a separated state, the distance between the main fuse moving contact and the main fuse static contact is smaller than the distance between the signal fuse moving contact and the signal fuse static contact, so that the device can realize linkage switching sequence operation by using a position difference, and is safe, reliable and convenient to operate. In addition, the electric driving module automatically controls the opening and closing of the insulating protective cover and the insulating base, thereby realizing the automatic control of the switching of the fuse.

Description

technical field [0001] The invention belongs to the technical field of DC power supply system equipment, and in particular relates to an easy-to-operate integrated storage battery pack fusing device with a visible protective cover. Background technique [0002] The substation is equipped with a station-use DC power system powered by batteries to provide power for DC loads such as relay protection, control, signal, and UPS in the station. At present, the outlet fuse device of the DC power system battery pack is composed of a main fuse, a main fuse base, a signal fuse, a signal fuse base and related secondary wiring. During the daily maintenance, regular inspection, and fault elimination of the DC power system of the substation, it is necessary to frequently switch on and off the fuse device at the outlet of the battery pack, and the following problems exist: [0003] 1. The safety protection performance of the fuse device at the outlet of the battery pack is poor. The dista...

AI Technical Summary

Problems solved by technology

[0003] 1. The safety protection performance of the fuse device at the outlet of the battery pack is poor

The distance between the positive and negative main fuses of the outlet fuse device of the battery pack in the DC panel is small, and the live parts are completely exposed. There is no insulating protective cover and isolation facilities. It is easy to accidentally touch it during operation and cause a DC short circuit, which will cause accidents such as equipment damage and personal injury.

[0004] 2. It is cumbersome to switch on and off the fuse device at the outlet of the battery pack

When exiting the fuse device at the outlet of the battery pack, remove the two pairs of signal fuses on both sides of the main fuse, and then pull out the secondary wiring quick-plug interface of each signal fuse or untie the signal fuse and connect the main fuse together. Finally, use the main fuse operating handle to remove the positive and negative two main fuses. This operation requires a total of 6 steps, and the operation takes a long time. Similarly, the operation sequence of the fuse device at the outlet of the battery pack is reversed and there are the same question

[0005] 3. It is laborious to switch on and off the main fuse at the outlet of the battery pack

The main circuit connection between the conductive rod of the main fuse and the base of the main fuse adopts a metal bayonet lap design. The lap joint needs to pass a large current, and the metal bayonet needs to clamp the conductive rod of the main fuse vigorously. There are problems such as oxidation and jamming at the overlapping parts of the metal bayonet, which makes the operator need to use a lot of effort to complete the operation of switching on and off the main fuse, and the ergonomics is poor.
